Nice article about math at Princeton (feature,
Nov. 7). I received my Ph.D.
at Princeton in 1958. The way we were told the story was that Solomon Lefschetz
invented the "N" grade. Albert Tucker *32 was chairman at a later period. Perhaps
the facts can no longer be determined.

By the way, there should have been a mention of the period under Tucker and
others when Game Theory was strongly developed in Princeton. After all, John
von Neumann, Oskar Morgenstern, and John Nash *50 all were key researchers in
that field. Ask Harold Kuhn.

And so many other names/fields were left out. I think Math@Princeton
deserves another article!
